The present invention discloses a wireless communication device including a slot antenna, a radio-frequency (RF) signal processing module for processing an RF signal transmitted or received by the slot antenna, and an RF signal diplexer coupled between the slot antenna and the RF signal processing module for splitting up the RF signal into a first frequency component and a second frequency component during transmission, and synthesizing the RF signal corresponding to the first frequency component and the second frequency component during reception.

Wireless communication device and feed-in method thereof

In an embodiment of the disclosure, an electronic device arranged for eliminating wireless noise interference is provided. The electronic device includes a circuit board and two first metal components. The metal components are arranged on different sides of the circuit board. Each of the first metal components comprises a first terminal and a second terminal opposite to the first terminal. The first terminal is coupled to the circuit board and the second terminal is open loop. The length of the first metal component is about one-fourth wavelength of a pre-determined frequency.

Electronic device for eliminating wireless noise interference

The present invention discloses a directional antenna for a multi-in multi-out or antenna beam switchable wireless communication system, including a substrate, at least one directional antenna, formed on the substrate, for generating a radiating pattern of a radiation plane according to a feeding signal, and a reflector, disposed in parallel to the radiation plane of the directional antenna, for reflecting the radiating pattern of the directional antenna, to increase a gain of the directional antenna corresponding to the radiation plane.

Directional antenna and radiating pattern adjustment method

The present invention discloses a high gain antenna. The high gain antenna includes a first dipole antenna, formed on a substrate; a parallel reflection metal sheet, formed on the substrate and in parallel with the first dipole antenna; a first vertical reflection metal sheet, vertically disposed on a front side of the substrate and behind the first dipole antenna; and a second vertical reflection metal sheet, vertically disposed on a back side of the substrate and behind the first dipole antenna.

High gain antenna and wireless device using the same

A antenna for transmitting radio signals of a lower frequency and a higher frequency includes a driven element comprising two first radiating units for a lower frequency band and two radiating units for a higher frequency band, and a reflector element comprising a first reflecting unit for the lower frequency band and a second reflecting unit for the higher frequency band. The second radiating units are disposed at a side of the first radiating units and respectively coupled to a corresponding first radiating unit. The first reflecting unit is disposed at the other side of the first radiating units, and the second reflecting unit is disposed between the first radiating units and the first reflecting unit.

Antenna and multi-input multi-output communication device using the same

A printed dual-band antenna for an electronic device includes a substrate, a first monopole antenna and a grounding metal sheet. The first monopole antenna is formed on the substrate, and has an electrical length approximating to a quarter wavelength of a first frequency band and a three quarter wavelength of a second frequency band. The grounding metal sheet is formed on the substrate to be a ground of the first monopole antenna. A feeding terminal of the first monopole antenna, formed at a first side of the grounding metal sheet, divides the first side into a first edge and a second edge. Lengths of the first edge and the second edge approximate to a quarter wavelength of the second frequency band.
